I'd wait about a week from now and give them all C/D-T. Reason being, the baby kid could use it then and you may as well just do them all at once. Just to be on the safe side, I'd personally booster *all* of them four weeks after that and then go yearly.
As for coccidia...the mama doe is probably OK at this point in her life, but the 5mo old is kinda in that borderline area where there could still potentially be a problem.. If she's grown appropriately so far and seems in good condition, she's probably already got coccidia under control on her own; if she's a little thin or ribby or kinda small for her age, I'd go ahead and get her on a treatment regimen..
You'll want to get DiMethox on hand for the kid anyway within the next two weeks. I've been using the the 40% injectable as an oral drench, dosing at 1ml/15lbs, 1x/day for 5 days starting at three weeks of age and doing three total treatments on three week intervals....3wks, 6wks, 9wks. Seems to be working for me and it's only about $20 for a 250ml bottle....pretty cheap stuff.
As others have mentioned, you'll also want to evaluate your worm situation. The baby's going to be coming onto grass at a
rough time of the year, because barberpole worms -- the most plentiful, the most pathogenic, and the hardest to kill of all worms -- are kicking it into warp speed right now in terms of egg production. That means they're cranking out lots of eggs, which lead to lots of larvae, which leads to heavy infestation, which leads to heavy blood consumption from the host, which leads to anemia and death..
If allowed to get out of control, anyway..
Mama and the 5mo could be the new kid's worst enemies right now, because they're the ones out there shedding all those eggs. Unless their lower inner eyelids are like
salmon colored indicating hardly any worm burden...I'd personally go ahead and deworm just for the baby's sake.
That's me, though.
